Scripts

		// 读取上次报错时间
		try {
			$fhRead =  @fopen("timestamp/$this->id.txt", "r");
			if($fhRead) {
				// echo "时间记录文件第一行".fgets($fhRead)."
";
				// echo "时间记录文件第二行".fgets($fhRead)."
";
				$lastSendEmail = strtotime(fgets($fhRead));
				$lastSendSms = strtotime(fgets($fhRead)); 
			}else {
				$this->logMesg("文件有误, 无法读取");
			}
		}catch (Exception $e) {
			$this->logMesg("读取报错时间记录文件遇到错误:".$e);
		}

2. 写入数据:

		// 记录报错时间.
		try {
			$fhMarkTime = @fopen("timestamp/$this->id.txt", "w");
			if($fhMarkTime) {
				fwrite($fhMarkTime, date("Y-m-d H:i:s",$upadtedLastSendEmail)."\n");
				fwrite($fhMarkTime, date("Y-m-d H:i:s",$updatedLastSendSms));
			}else {
				echo "文件写入错误.";
			}
		}catch (Exception $e) {
			echo "文件写入错误: ".$e;
		}

PHP Array 简单操作小结

Categories: PHP; Tagged with: Array • PHP • Php Array; @ August 28th, 2010 11:32

1. 创建Array: $arraySites = array();

2. addItem: $arraySites[$site->id] = $site;

3. 使用foreach遍历Array:

foreach ($arraySites as $site) { // 遍历每一个Site.
	// do something.
}

// Or:
foreach($array as $key=>$value)
{
echo "$key,$value ";
}

4. length: count($arraySite);

5. 打散/切割 Array : array_chunk($mails, $MAX_MAILS_PER_SMTP_SESSION, true);

该方法将会根据设定的大小对原数组进行切割, 生成多个小的数组(最后一个可能会少于单元大小), 第三个参数控制是否在打散后的数组内保留其原有key.
